FORMER MINNESOTA STATE Sen. Matt Little was lawfully observing federal immigration agents in a Dakota County neighborhood last month when the drive took an unexpected turn.

As he followed their vehicles, they led him down a rural road that grew increasingly familiar during the 20-minute drive. Soon, Little told The Intercept, he realized where the federal agents were headed: his house.

When he approached his driveway, two SUVs were already waiting, Little said. Agents moved to block his car, claiming he had impeded their investigation and that local law enforcement would be called. No other officers came to his house, and Little was not cited or charged.

Interviews, sworn declarations, and video reviewed by The Intercept indicate that Little is not the only person subjected to this kind of intimidation. Across the Twin Cities, immigration agents have identified legal observers by name and address, and, in some cases, led them back to their homes after they engaged in lawful monitoring of immigration activity. Legal observers say this pattern of behavior sends a clear and chilling message: The federal government knows who they are and where they live.
